3D Modeling

Begin by defining the model's purpose (e.g., game asset, product visualization, print). Collect or generate reference images from multiple angles. Use AI image generators (Midjourney, DALL-E) to explore style variations or create orthographic sketches if no existing references exist. Sketch rough proportions on paper or in a 2D app to lock in the design intent before moving to 3D.

Why Midjourney: Midjourney is a leading AI image generator that directly matches the need for generating concept images from text prompts, and it supports creating variations and editing, which aligns with the reference gathering and ideation phase.

Using your 3D software (Blender, Maya, 3ds Max), create primitive shapes (cubes, spheres, cylinders) to block out the overall silhouette and proportions. Focus on scale and mass, not detail. Use mirror modifiers for symmetry when applicable. This step validates the design in 3D space before investing time in fine geometry.

Convert the blockout into a high-resolution mesh (subdivision or multiresolution) and use digital sculpting tools (ZBrush, Blender Sculpt) to add organic details, creases, and surface imperfections. Work from large forms down to micro-details. For hard-surface models, use subdivision modeling with edge loops and bevels instead of sculpting.

Create a new, clean low-poly mesh that wraps around the high-detail sculpt (or refine the existing mesh for hard-surface). Use quad-based topology with proper edge flow for animation deformation. Tools like Blender's Retopoflow, Maya's Quad Draw, or automatic retopology (Instant Meshes) speed this process. Ensure all faces are quads and poles are minimized.

Unwrap the low-poly model into 2D UV islands, minimizing distortion and maximizing texel density. Pack islands efficiently within the 0-1 UV space. Then bake high-poly details (normal maps, ambient occlusion, curvature) onto the low-poly mesh using the cage method. This transfers sculpted detail without geometry cost.

Create or assign PBR materials (base color, roughness, metallic, normal) using a texturing tool (Substance Painter, Quixel Mixer) or node-based shader editor. Layer smart materials, masks, and hand-painted details to achieve the desired surface appearance. Preview in the target render engine (Eevee, Cycles, Unreal) to ensure material response to lighting is correct.

Why Meshy: Meshy provides AI-driven PBR texturing and 3D generation, which directly supports material application and look development in a 3D workflow.

Export the model in the required format (FBX for games, OBJ for printing, USD for pipelines). Ensure scale, orientation, and pivot points are correct. Package all texture maps in the appropriate resolution and format (PNG, TGA, EXR). Optionally create LODs (Level of Detail) for real-time engines. Generate a thumbnail render and a brief documentation sheet for the asset.

Why Matterport: Matterport supports 3D space capture and BIM file export, which aligns with the need for final export and delivery packaging of 3D assets.
